Hello there Fellow SAABers ,

I have got a question regarding the compatibilty of an 1989 900 t16 us. 5spd trans. with an 1984 900t 8v us. engine. also whether the eingine and trans. out of an 85' 900 t16 us. would work out in the 89' 900 t16. I'm aware of the watercooled lines for the turbo bearing. I just havent done one in awhile 3yrs so any info about this would be very helpful with getting my WHOLE FLEET up and running again!!! Just been workin' on alot of overpriced "GERM's" these days!!:lol:

damn those AUDI's!! I gotta admit it I personally own 2 Quattros , an 83' Ur Quattro GT 2.3 5 cylinder 10v turbo and an 89' 200 Quattro 2.3 5 cylinder 20v turbo. But theres nothing like my 81' 900 8v Turbo!!! :D

As for the the engine/trans compatibility, they will bolt up. Compare the gear ratios -- I forget where those are located.

The motor swap is a bit trickier -- the engine should be good (I would try to keep the water-cooled turbocharger, if possible), but look into the electrics to make sure that the two are an easy swap. I would look at wiring diagrams from the 85 and the 89 to see what differences there are.

Hope that it works out.

89 has LH 2.4 85 has LH 2.2. You want LH 2.4 so keep any fuel injection parts (especially AMM) of 1989 spec. The older motor also has external oilers on the camshaft, you'll see that when you take off the valve cover. No biggie however, the later internal design is cleaner to the eye but they both do their job well.
